Identify the formula of the corresponding hydrideof a nonmetal 'X' whi

1.	Identify the formula of the corresponding hydrideof a nonmetal 'X' which attainsoctet by gaining three electrons.
Answer» XH `XH_(2)` `XH_(3)` `X_(2)H_(4)` Solution :X'should possess five valence electrons . Since its valency is 3. Hence , its corresponding hydride is`X^(-3)H^(+1)rArrXH_(3)`
